自动化的Windows防火墙

本文介绍了自动化的Windows防火墙的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我有一个使用端口777与我的SQL Server通信异步通信和3306端口C＃应用程序。当端口被防火墙阻止，就会出现问题。我试图创建一个程序在Windows 7的防火墙列表中添加一个例外 当我运行程序时，我得到的错误如下：灾难性故障（例外来自HRESULT：。0x8000FFFF（E_UNEXPECTED）） 我不明白这些错误的意思是，任何的建议是值得欢迎的，谢谢 受保护的内部空隙AddExceptionToFirewall（）{尝试{ INetFwMgr防火墙= NULL;
